'British Scareways'

With the headline "British Scareways", the Sun says BA pilots are plotting a ten-day "mega strike" in November to "break" the airline, as part of their ongoing pay dispute. A source is quoted as saying "the disruption seen so far is nothing" and the walkout would bring BA "to its knees".

The paper argues the pilots' union, Balpa, "has to give way" and calls on BA's parent company, IAG, to "clear up this mess before it gets any worse". Balpa, meanwhile, has tweeted to say the story "is nonsense".

The paper says the memo forms part of Labour's "preparing for government" strategy, with Mr Corbyn's inner circle "increasingly confident" they may be in Downing Street by Christmas. Labour declined to comment on the story.
